Document Summary
Transmission: uninterrupted passage of shortwave and longwave energy through atmosphere or water o. Energy: capacity to do work or move matter. Heat: flow of kinetic e between molecules and from one body to another resulting in t difference. Sensible heat: from kinetic e of molecular motion. Latent heat: e gained or lose when substance changes from one state to another. Conduction: molecule-to-molecule transfer of heat e as diffuses through substance. Stuff in atmosphere interact with radiation causing it to change direction. Diffuse radiation: incoming e that reaches earth"s surface after scattering occurs. Direct radiation: straight line to earth"s surface without being scattered. Rayleigh scattering: shorter wavelengths scattered more, longer scattered less. Blues shorter wavelengths and scattered most throughout atmosphere. Mie scattering: process that works on particles larger than wavelengths of light. Transitions that change speed of insolation causing it to change directions.
